, the accompanying drawings, .is a specification, like letters on the drawings representing like parts.

lThe inventionl tol-be hereinafter described relates toscouring machines for boots and shoes, and more particularly to the guard for heel scourers.

The object of the present invention is to provlde a simple and eilicient device for protectingl the upper or other portion of a.

oot or shoe from injury during the scouring or lpreliminary iinishing operation of the heel thereof. As Well known b those skilled in' the art, the heel portions o bootsand shoes, as part of the finishing operation, are subjected to the Y'abradingpr scouring action of a suitable element, such as an emery or other rough surfaced wheel, and that as the boot or shoe is turned to bring all portions of the l -heelfinto operative relation to the scouring element or wheel, the upper or sole ofthe shoe 'is liable to be injured by contact with the scourer, particularly as the edge ofthe heel joining the breast and exterior heel contour is approached. This is true at thebeginning of the operation when the operatorplaces the heel in position With the toe of the shoe preferably pointing upward, but at such times the operator can gage the shoe position by the eye and touch so as to'overcometh'e di'fiiculty. y As the toe of the shoe is turned downward, however, -to bring the opposite side and edge of the breast line into operative relation i with the scourer, ,it frequently happens that some portion of the shoe in front of the toe contacts with the scourer, resulting in -injury'to the shoe, as is well 'i understood by those skilled in the art,.the

present invention being designed to overcome this defective action of the scourer and resulting injury to the work.

The invention will best be understood l from the following detail descriptionand scope being definitely pointed out in the Vclalrns.

j In the drawings :-Figure 1 is a front elevation of one forni of scourer with the present invention applied thereto. Fig. 2 is a cross section on line Fig. 1. Fig.` 3 is an enlarged 'dtail showing the scouring' wheel and guard' in operative relation. Fig. 4 1s a detail sectional view on line Ay--y, Fig.

3. Fig. 5is a detached detail of the hinged arm of the guard bracket, looking inthe direction'of the arrow, Fig. 3.

' The standardA, thehead B carrying the scouring shaft. 1, the hood. 2 covering the shaft driving wheel or other element,` and the deflector 3, may be ofany usual or desired character and associated Vfor the particular work. to be done.

Mounted upon the shaft 1, are the scouring wheels 4, 4, two being shown assembled on the one shaft,.but, obviously, the number of such wheels is immaterial, and said wheels may be'formed of any desired character-of abrading material.'l f

In scouring the Aheels of boots the operative usually presents the heel to the scouring wheel with the toe ofthe shoe pointing upward and commences the scouring action on the side of the heel at the breast line, as indicated by'dotted' lines in Fig. 2L such time the operative, looking down -in about the general direction of the arrow, .F ig.

and shoes,

2, can place the side of the heel properly against the scouring'wheel- 4, and, by the eye,

so gage'the position of the shoe that the upper or sole will not contact ywith the scouring wheel. As the shoe is turned from the 4dotted to the full line position in' Fig. 2 to bring all ortions of the eel into working contact wit the scouring wheel, the Wheel and shoe obstruct'the view of theoperative, so that as the .final portions of the heel adjacent the i relation to the Working portion of thewheel', j

that asfthe shoe is turned to` com lete the work on theheel, the forepart Wil contact with the movement ofthe shoe. ,f i

In the' form of guard selected for ,exploita tion ofthe invention, abracket arm5 iss- 110 as the bolts 6, said bracket arm being Iro-y i cured tothe head B bysuitable means such guard and arrestv further4 turning.y

'vided at its endadjacentthe scouring w eel i the bottom.

clamp nuts 14, 14.

allow a greater range of turning movement 'to the shoe before the orepart contacts with the foreward edge 12,. By this expedient, as

will be readily understood by those skilled in the art, the o erative is enabled to present' all )arts of the eelto the action ofthe secure?, an turn the shoe suliciently to finish the scouringat the breast line of the heel without liability of injuring the forepart of thc shoe.

In the scouring of heels oi dilierent sizes or kinds of boots and shoes it is necessary to adjust the guard platev 10 so'that the protecting portion 11 .will extend more or less aboutthe scourer 4; and indeed this adjustment is desirable even with different operatives on the same kinds or sizes of shoes, because different operatives will'use different portions of the scouring wheel 4,'some using a portion nearer to the top'andsome a portion nearer In either event, the guard plate 10 is readilyadjustable by simply loosening the bolts 9 moving it to the position desired, and thensetting the bolts. f

The'bolts 9 and their clamping action may be of any desired character, but in the drawings they are shown as having one end secured to the side 'flange of the guard plate 10 as at 13, the other end 'being extended through the curved slot 8 of thebracket arm and vprovided with a screw thread for the' It is sometimes desirable to move the guard plate and its adjuncts to onel side either for cleaning7 removal of the scourer 4, or other purpose, so that the present invention, while not restricted to a two part jointed bracket arm, embraces a construction, such as shown, wherein the bracket arm 5 is forinedot two parts joined together bya hinge or like device,as indicated at 15, Figs. 3 and 5; In such construction one member of the bracket arme is preferably provided with a stop 16 to prevent the outer member or' the bracket 'arm which carries the guard plate freni being moved into contact with side of the scourer Likewise to hold the outer meinber inA proper operative relation with the scourer 4. a catch or'lock 17 is pivoted at 13 and provided -with wings 419, whereby, it may be turned either into the position indicated `in Fig. 3 to lock 4the Vhinged members ui the bracket arni, in proper relationfor theguard plate 1G to perfornrits'guarding function, or

up-ward'fat substantially ri ht angles to j position, as will be readi y understood by those skilled in theart, to unlock the bracket arm members and permit the outer arm to be swung to one side.. 7Vhen the catch or lock 17 is in position as indicated in Fig. 3, a stop 2() limits its turning movement by contact with a projection 21 extendingfroin the catch or lock 17.

' In describing the invention theoperatife has been presumed to. commence the scourmg action upon the heel with the toe ofthe shoe pointing upward, and gradually turniiw the toe downward from the dotted'to the line osition, Fig. 2, and this is, infact, lthe usua method ot procedure, but, obviously,

the inventionis not circuinscribed by such limitations, its essential-boing that it shall be so disposed with relation to thescourer, that as the shoe' approaches a position calculated to bringthe fore-part into 'contact with the scourer, the guardwill act to prevent such contact. V

I t will be noted that the portion 7 of the bracketfarin `and 'the flano'e 'of the guardplate 10 substantially parallel thereto, pro# toct thesdeo'f the scourer 4, so that no part ofthe-shoe can contact with this portion ci the wheel. v
